A new Leptographium species from Russia

Taxonomy and phylogeny of the Leptographium procerum complex, including Leptographium sinense sp. nov. and Leptographium longiconidiophorum sp. nov.

“…Leptographium longiconidiophorum and L. pini-densiflorae have been recorded only from Japan (Masuya et al 2000; present study), while L. bhutanense is from Bhutan , and L. sibiricum from Russia (Jacobs et al 2000). Most of these species were isolated from pines, but L. gracile (in Group A) has also been collected on spruce (Paciura et al 2010), and L. sibiricum (in Group C) was isolated from Abies (Jacobs et al 2000). The insects associated with species in Groups A and C are mainly weevils and bark beetles, with L. sibiricum being the only exception and collected as an associate of a cerambycid beetle (Jacobs et al 2000).…”

“…Three of these (L. gracile, L. sinoprocerum, L. sinense) have been reported only from China (Lu et al 2008;Paciura et al 2010; and isolates from the present study). Leptographium longiconidiophorum and L. pini-densiflorae have been recorded only from Japan (Masuya et al 2000; present study), while L. bhutanense is from Bhutan , and L. sibiricum from Russia (Jacobs et al 2000). Most of these species were isolated from pines, but L. gracile (in Group A) has also been collected on spruce (Paciura et al 2010), and L. sibiricum (in Group C) was isolated from Abies (Jacobs et al 2000).…”

Pathogenicity has been tested for only L. sinoprocerum residing in the Asian lineages.…”

“…At present, the L. procerum complex includes eight species (Linnakoski et al 2012). Interestingly, apart from L. procerum (Kendrick 1962) and L. profanum described from USA, and L. sibiricum from Russia (Jacobs et al 2000), all other species in the complex have been described from East Asia (Linnakoski et al 2012). Leptographium pinidensiflorae was described from Japan (Masuya et al 2000), L. bhutanense from Bhutan , and L. sinoprocerum (Lu et al 2008), L. gracile and L. latens (Paciura et al 2010) from China.…”

Host Volatile Attractants and Traps for Detection ofTetropium fuscum(F.),Tetropium castaneumL., and Other Longhorned Beetles (Coleoptera: Cerambycidae)

“…Fresh pine stumps also serve as hosts for S. buprestoides (Jakaitis and Valenta 1976) and T. castaneum (Sama 2002), and in Asia, both species may colonize the same host along with A. striatum (Cherepanov 1988). M. urussovii breeds in dying, recently cut, or windfelled Abies, Pinus, and other trees (Isaev et al 1988), and vectors a blue-stain fungus, Leptographium sibiricum (Jacobs et al 2000). It is somewhat surprising that ethanol did not synergize attraction of A. striatum or M. urussovii to monoterpenes, because both species breed in hosts (e.g., stumps or weakened trees) that reportedly have elevated ethanol concentrations.…”
